ABSTRACT:
A composite article includes an acrylic layer, a UV-cured layer formed from a UV-curable composition, and a polyurethane backing layer. A method of forming the composite article includes applying the UV-curable composition to the acrylic layer such that the composition is between the acrylic layer and the polyurethane backing layer to enhance bonding between these layers. The UV-curable composition includes at least one monomer which is an ethylenically unsaturated methacrylate monomer, an ethylenically unsaturated acrylate monomer, or both. The at least one monomer has a hydroxy functional group. The monomer is compatible with the acrylic layer and the hydroxy functional group of the monomer is reactive with a polyisocyanate from the polyurethane backing layer. The UV-curable composition also includes a curing initiator that is reactive with the monomer. Upon exposure of the UV-curable composition to UV electromagnetic radiation, the curing initiator enables the composition to cure to the acrylic layer.
